IMPROVEMENT lN WAGON-SPRINGS.

Specification l'orniing part ol' Letters Patent No. 214,584, dated April 22, LQTSI; appication Iiled February 26, 137i).

To all whom it may concern:

Be it known that I, LUTHER PULLIAM, of Miami, Saline county, Missouri, have inade a new and usei'ul Iinlirovement in Ia-gon- Springs, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this speciiication, in which- Figure l is a view, in perspective, of the spring; Fig. 2, a perspective, showing' the `springs in position upon the bolster, and Fig'.

3 an elevation, showing the invention in position, with the wagon-bed resting upon the springs.

The same letters denote the same parts.

The present invention is especially adapted to 'farm-wagons. It is simple in its construction, easily inade, and readily operated. It is detachable, so that the wagon can be used either with or withoutthe spring, and it is so shaped and attached as to enable it to support the wagon-bed when an ordinary load is being carried, but when an unusually heavy load is being carried to yield sufficiently, and so that the wagon-bed is sustained, practically, by the bolster.

A further advantage is, that the weight is sustained by the bolster at or near the center ofthe latter, instead or' at the ends thereof.

Referring to the drawings, Arepresents the improved spring. Itcousists, mainly, of the spring proper, c, and a clip, c1, for attaching the spring to the bolster B. It is also preferably provided with a plate, a2, upon which the wagonbed immediately rests, and which, to prevent the bed from chaiing the spring a, is raised slightly above the top of the latter.

The clip al is shaped to iit upon the bolster D, the flanges a a3 extending downward against the i'ront and rear faces b b of the bolster.

O represents a pin or other projection with which the bolster is furnished, and extending outward from the bolster, so as to engage in the slots at ai in the iian ges a3 a3, for the spring is fastened in position by turning it so that the pin O enters the slots a* at, and then into the posit-ion shown.

The plate a2 is notched at a5 to receive the standard D.

The springs are used in pairs A A', as shown in Figs. l and 2.

E represents the wagon-bed. The stainlards D D are provided with a scale, d d, suitably graduated, to indicate the weight ot" the load being carried. The plate a2 acts, also, as a pointer upon these scales, enabling' the weight to be more readily and accurately i11- dicated. As the load is increased the sprin yield, and the pointer a? moves down upon the scale.

By attaching scales to all the standards, the load can be accurately determined by averaging the weights indicated on the various scales.

I claim* l. The herein-described wagon-spring A, consisting of the spring a and clip al, Ain combination with the bolster I3 and pin U, substantially as described.

2. The combination of the spring A, having the spring a, clip el, and plate a2, the bolster B, pin C, and bed E, substantially described.

3. The springs A A', having the clips al al and springs a a, the bolster B, and pins O O, substantially as described.

et. The combination oi" the springs A A', bolster B, pins O O, standards D D, scales d d, and bed E, substantially as described.

L. PULLTAM.
